20 dB gain on 20 meters?!?

Then for another 3 db, he would have to add yet another twelve stepirs. The second three steppirs only gained him 3 db over the first three and the second steppir only gained him 3 db over the first one. so, what does that three db mean?

Three Db equals a doubling of power or halving of power depending on which way you are going. Dave WD9BDZ If I looked at his numbers right, his vertical stacking is way too close (1/2 wave), and he won't get 3 DB. OTOH, he got himself a super 6 m antenna. Possibly enough for moonbounce.
